Amazon Web Services team:
You can now host an entire website on Amazon S3. You can now configure and access any of your S3 buckets as a “website.” When a request is made to the root of your bucket configured as a website, Amazon S3 returns a root document. Not only that, if an error occurs your users receive an HTML error document instead of an XML error message. You can also provide your own error documents for use when a 4xx-class error occurs.
S3 is a great service, and this is a great solution for people that don’t need things like SQL.
